QM33120WDK1 Doesn’t power up

Wireless Connectivity Ultra-Wideband
1

Hi,

I purchased the QM33120WDK1 from mouser and the board doesn’t connect to PC over USB connector(J3) on nRF52840DK.

I only see D1,D2 LED blinks for a second but PC doesn’t even detect the USB connection. As per quick user guide, there is no instruction other than connecting USB and running QorvoOne.

I am using Windows 11 Pro

Just FYI, JLink Debug Connector(J2) seems to atleast show up in device manager.

Regards,

Kaushal

When connected to J2, do you get a serial port and can connect with a serial console? If so can you try type “?” or “stat”?

I have the same problem with this Kit. Also from Mouser.
QorvoOne is not detecting any devices conected throught USB.
I also see leds flashing for a second…
I’m using Iwndows 10 Pro.
How to solve this?
Thank you

Also, you can flash the UCI binary with Flash Lite application, to be sure that you have the SW running.

Switches are in the correct position.
Is there a manual to flash in the easiest way the UCI binary with Flash Lite application?

Thank you

@fmasso , check in the developer guid document inside the SDK the section 4 “Flashing SDK Firmware”.

Thank you @Wassim_Qorvo. It works!
The product from Mouser comes without preprogramed firmware.
But Qorvo guide says are preprogramed!

Thanks!

Hi, I have come across the same problem.
But when I try to flash SDK Firmware by using JFlashLite, it shows that no probes are connected via USB. How can I solve the problem?

Hi @Sending ,

You need to plug in your board by using the J2 connector in the picture above. After the flashing is done, you can use the J3 connector to communicate with the QM33.

Kind regards,

Yeah, I have solved the problem. The problem lied in the USB driver.
Before running J-link, I need to run instDriver.exe.

Thanks for your reply.

Hi @Sending, can you please post the serial numbers of your boards. They are on the sticker on the red boards and should be in the format Q1yywwxxxx and Q2yywwxxxx. We want to figure out why/how they have been shipped without firmware. Thank you.
